DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 561 ,432, dated June 2,1896.

Serial NO- 558,703. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. PLUMMER, of \Vinchendon, in the county ofWorcester and State of Massachusetts, have invented a new and usefulImprovement in Dumping- WVagons, of which the followingis a full, clear,and exact description.

My invention relates to dumping-wagons; and the object of the inventionis to so construct a dumping-wagon that while the body of the wagon isfulcrumed over the rear axle a portion of the load will be carried bythe forward axle in a four-wheeled Vehicle.

Another object of the invention is to so hang and mount the body of thevehicle on the running-gear thereof that no matter how heavy the loadmay be in the body the body may be carried from carrying to dumpingposition by the action of the team, thereby dispensing with the servicesof an attendant or attendants in the dumping operation.

Another object of the invention is to so mount the body of the wagon onthe runninggear that when the body is dumped the entire vehicle may bedrawn forward and the body carried away from the load.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a partial side elevation of the improved du1nping-wagon, thewheels upon one side being removed and a portion of the reach and one ofthe fastening devices being in section. Fig. 2 is a view similar to Fig.1, the body of the wagon being in dumping position; and Fig. 3 is a planview of the running-gear of the wagon, the body having been removed.

In carrying out the invention the rear axle 10 is provided with theusual ground-wheels 11 and is connected with the forward axle 12 throughthe medium of a reach 13. The said reach at its forward end has alongitudinal slot let made therein, as shown in Figs. 1 and 2, and theking-bolt 15 is passed through this slot and into the axle. The wheels16 of the forward axle are preferably smaller than those of the rearaxle. The reach is also provided with a metal loop or yoke 17, locatedto the rear of its slotted extremity and somewhat adjacent thereto.Tlhis yoke or loop extends some distance above the reach, and thestraight member of a horizontal T- shaped push-bar 18 is passed throughthis loop, being parallel with the reach, and preferably at the forwardend of the push-bar a metallic strap 19 is horizontally secured, and theking-bolt 15 is passed through this strap, buthas no lateral playtherein, being simply loosely mounted in said strap.

The rear and head member of the pushbar, the longer forwardly-extendingmember being preferably the shank, is provided at its ends with pins 20,and these pins are held to slide in staple-like bearings 21, locatedupon the top of the rear axle and upon forward extensions 10 of the saidaxle, as shown in Fig. 3, and at the rear central portion of the rearaxle a roller22 is j ournaled on the top thereof. The wagon-body 23 isprovided with eyes 24 or their equivalents, placed slightly forward ofthe center, one at each side, and these eyes are held to travel-on thestaple-like bearings 21, as is shown in Figs. 1 and 2. The eyes,however, are back of the pins of the push bar and are adapted to beengaged thereby.

At the front of the body 23 a horizontal lip 25 is secured in anyapproved manner, and .the said lip is provided with an opening adaptedto register with a corresponding opening in the top of the yoke 17 whenthe body is in carrying position, the lip being carried within the yoke,yet above the push-bar, when the body is in horizontal position, asillustrated in Fig. 1, and the bodyis held in this position by passing apin 26 through the openings in the yoke and the lip of the body andlikewise in the push-bar and reach.

It will be observed that while the major portion of the load issustained by the rear axle a portion of it is borne by the forward axle,and that when the locking-pin 26 is in lockin g position the reach,push-bar, and body of the vehicle are held stationary, while the eyes ofthe body are considerably forward of the rear axle, and in proportion tothe distance the eyes of the body are carried to the front will be theamount of Weight to be sustained by the forward axle.

WVhen the load is to be dumped, the pin 26 is removed and a block isplaced behind the rear Wheels, as shown in Fig. 2. The team is thenbacked, whereupon the forward axle will be carried rearwardsubstantially the length of the slot 14: in the reach and the push-barwill be carried by the king-bolt in the same direction. This will causethe pushbar to force the sides of the body along the bearings over therear axle, and the moment that these sides have reached a point on thebearings at which the weight of the load will be carried past the centerthe body will drop to dumping position, as illustrated in Fig. 2. Thevehicle may now be drawn forward in order to free the body from contactwith the material dumped.

It is evident from the foregoing description that the team will performall of the work of dumping, and that an exceedingly heavy load may bedumped with much more ease than a light one under the old construction,the roller 22 over the rear axle serving to greatly facilitate thetravel of the body over the runnin ggear.

By placing a portion of the load upon the forward wheels a team can drawfrom onefourth to on e-third more of a load than if the load wassupported by the hind wheels alone.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-.

1. In a vehicle, the combination, with an axle, a reach attached to theaxle, and abody mounted to slide over the said axle, of a pushbarprovided with portions for engaging the body and having sliding andguided movement in the reach, and loekin g devices adapted to secure thebody to the push-bar and reach, as and for the purpose specified.

2. In a dumping-vehicle, the combination, with an axle having a forwardextension near its ends, a reach secured to the axle, bearings attachedto the axle and its extensions, and a body mounted to slide on the saidbearings, of a push-bar having sliding and guided move ment on thereach, being adapted in its rear-' ward movement to carry the body todumpingposition, a keeper secured to the reach, through which thepush-bar passes and has sliding movement, a lip attachedto the body,adapted likewise to be passed within the keeper, and a locking-pinadapted to be passed through the keeper, body-lip, reach and pushbar, asand for the purpose set forth.
